Definitions
- the present invention relates to a curved suspended ceiling having a grid of inverted T beams suspended from a structural ceiling, with drywall boards fastened to the grid.
- Suspended ceilings in rooms are common. They have a grid of metallic beams that is suspended from an overhead structural ceiling, as by wires.
- the metallic beams used in the grids of suspended ceilings are made in a continuous process.
- a continuous strip of metal, usually steel, fed off a reel, is passed through a series of rolls that form the metal into an inverted T cross section having a web, a bulb at the top of the web, and horizontal flanges extending from the bottom of the web.
- Such beam construction is well-known.
- a straight, finished beam continuously emerges from the roll forming operation, and is cut, on the run, into suitable lengths, of, for instance, 12 feet, or 4 feet, or 2 feet, with, for instance, a flying shear. Connectors are then formed at the ends of the straight beam lengths. The beams are then stacked and packaged for shipment to the job site for assembly into the grid of a suspended ceiling. The beam cross section gives the beam rigidity throughout these operations.
- the beams are formed into a grid at the job site, in the well-known prior art manner, by means of the connectors at the ends of the beam.
- Such grid has parallel main beams that are connected by cross beams.
- a panel suspended ceiling panels are laid in the grid openings and supported by the flanges of the beams.
- drywall boards are attached to the beams of the grid by screws.
- suspended ceilings that are curved are installed, particularly of the drywall type.
- a grid of curved main beams, connected by straight cross beams, is suspended by wires from a structural ceiling, and drywall boards are then attached to the grid by screws, as in a horizontal drywall suspended ceiling.
- the faces of the drywall boards are wetted and then are bent to the desired shape prior to attachment to the grid.
- a segment of the bulb is left in place above the cutout to maintain the integrity of the straight beam.
- the cutouts are manually extended through the remaining segment of the bulb at the job site with a minimum of cutting and no need for measuring, and the beam is bent to the required radius, at the cutouts, between facets. Splice plates are applied over the extended cutouts at the bend to fix the beam at the desired faceted curve.
- Drywall boards are then attached, from underneath the ceiling, to the beam flanges, as by self-tapping screws.
- the faces of the drywall boards are wetted, and then are curved to the desired shape to conform to the faceted grid, prior to attachment to the grid.
- the present invention is for an improved splice plate in the curved beam disclosed in the '850 application.
- the splice plate of the invention can be used in both a convex curved and a concave curved main beam by merely inverting the plate.
- the plate permits cross beams in the grid to be connected through a slot in the plate. This positions the cross beams at the apexes of the faceted curves of the main beams.
- the curved drywall contacts the ceiling grid at the apexes, and at the cross beams, to which the curved drywall can be attached by self-tapping screws in the well-known prior art manner. This was not possible with the grid of the '850 application, since the cross beams were connected to the curved main beams away from the apexes, where the curved drywall did not contact the cross beams.
- the concave curved main beams of the present invention can be suspended from the structural ceiling at the splice plates, and again, as in the convex curved ceiling, the curved drywall can be screwed directly into the cross beams at their points of contact between the drywall and the cross beams.
- the cross beams extend between the curved main beams at points midway along the chords of the faceted beams. It is at these points that the curved drywall contacts the ceiling grid.
- convex curved main beam 37 or a concave curved main beam 39
- a straight beam 20 of inverted T cross section having a bulb 21, web 22, and horizontal flanges 23 and 25, as disclosed in the '850 patent application.
- Roll forming of a straight beam 20 is well-known in the prior art.
- the straight, finished beam 20 continuously emerges from the roll forming operation, it is continuously cut into suitable lengths, for instance 12 feet, or 4 feet, or 2 feet, as with a flying shear. Connectors, well-known in the art, are formed on the ends of the straight beams 20. The beams 20 are then stacked and packaged for shipment to the job site for assembly into the grid of a suspended ceiling.
- Cutouts 30, as seen in Figure 3, are continuously formed in the straight beam 20 as the straight beam 20 is continuously being roll formed in the roll forming operation, as disclosed in the '850 application, before the continuous beam is cut into lengths.
- the cutout 30 itself, as seen particularly in Figure 3 of the present drawings, is generally a vertically disposed rectangle 32 with a V shaped bottom 33.
- the cutout 30 leaves a segment 34 of the bulb 21, which is selectively cut out at the job site as will be described, and a web portion at the bottom of the cutout 30, in place in the straight beam 20, to provide rigidity to the beam 20 at the cutout 30.
- the beam 20 maintains its rigidity for handling, including cutting the continuous beam 20 into lengths, as described above, forming connectors at the ends, packaging, shipping to the job site, and handling at the site.
- the beam 20 with the cutouts 30, before being formed into a curved beam 37 or 39, is also of sufficient rigidity to be used as a straight beam where needed.
- the cutout 30 can have representative dimensions of .625 inches in width and 1.337 inches in height, in a beam having an overall height of 1.696 inches, as shown in Figures 3 and 4.
- the beams 20 of the invention are intended for use as main beams in a suspended curved drywall ceiling having concave, or convex, curves as viewed from below.
- selected cutouts 30 along the beam 20 are cut at the job site by simply slitting across bulb segment 34, for instance, as seen in Figure 3, with shears.
- the beam 20 is then bent at 36, as seen in Figure 5, to the desired faceted convex curve to form, as shown in Figure 1, prior art, or main beam 37, the beams 37 or 39 of the present invention, as seen in Figures 5 and 7.
- splice plate 50 replaces splice plate 27 as seen in Figure 1, as is disclosed in the '850 application.
- the splice plate 50 of the invention is used to fix the curve of the main beam in both a convex curved main beam 37 and a concave curved main beam 39.
- Plate 50 is divided into a portion 51 and a portion 52 by step 53.
- Portion 51 is rectangular in shape, having a dimension of, for instance, 2.0 inches wide, and .790 inches high.
- Portion 52 has the same width as portion 51, and has a symmetrical angular portion 55 with an apex angle of 180o.
- Portion 52 has a height dimension of .875 inches from step 53 to the apex 56.
- a slot 57 extends as shown centrally and vertically in portion 52.
- Such slot is of the type shown in United States Patent 6,178,712, incorporated herein by reference, and is intended to receive the connectors on the end of the cross beams to form a grid, as is well-known in the prior art.
- Holes 61 having, for instance, a diameter of .125 inches extend through the plate 50 at the locations shown.
- the splice plate 50 is applied to the bent convex curved main beam 37 at the bends 36, with the angled portion 52 of the plate 50 positioned at the bottom and against the web 22, and the upper portion 51 against the bulb 21 of beam 20, as seen in Figures 3, 4, and 5.
- the step 53 of the plate 50 is of a dimension that provides such fit, for instance, .10 inches.
- the plate 50 is arranged so that the slot 57 is in line with the opening 58 that remains when the straight beam 20 is bent into convex form to form convex curved main beam 37.
- the plate 50 is attached to convex curved main beam 37 with self-tapping screws 60 that extend through holes 61 and 62 into the web 22 and the bulb 21 of the beam 37 as seen in Figures 4 and 5.
- the convex curved main beam 37 is then suspended from a structural ceiling by suspension wires 66 through holes 64 in the beam, in the well-known prior art manner.
- Cross beams 67 are secured to the convex curved beam 37, which acts as a main beam of the grid. Connectors on the end of the cross beams 67 are stabbed through slot 57 to secure opposing cross beams to each other and to the curved beam 37, in the well-known prior art manner. Such an arrangement is shown in the '712 patent referred to above.
- cross beams 67 In inserting the cross beams 67 into the slot 57 of plate 50, it may be necessary to slightly bend the flanges of the a cross beam 67 at the ends thereof to conform to the apex angle of the convex curved main beam 37 to avoid interference from the flanges 23 and 25 when the cross beams 67 are inserted, as shown at 68 in Figure 5. This can be readily done at the job site with pliers.
- Drywall boards 70 are then attached to the grid, as seen in Figure 5.
- the faces of the drywall board are wetted, and the board 70 is curved to the desired shape to conform to the curved grid, prior to attachment to the grid.
- the curved drywall 70 will come into contact with the curved grid along cross beams 67, which extend between the convex curved main beams 37 at the bends 36 which are fixed by the splice plate 50.
- Self-tapping screws 71 extend through the drywall 70 into the cross beam 67, in the well-known prior art manner.
- the splice plate 50 of the invention is inverted, and applied to the beam 39 as shown in Figures 6 and 7.
- the curved beam is supported by wires 66 that extend from slot 57 in the inverted splice plate.
- Cross beams 67 are inserted into the curved main beam 39 in slots 72 in the web 22 at the middle of the chords of each facet of the beam 39, since it is at this location that the curved drywall boards 70 will come into contact with the grid, as seen in Figure 7.
- Self-tapping screws 71 secure the drywall board 70 to the cross beams 67 to form a concave curved drywall ceiling.
